Fourth quarter 2016 production growth of 12% year-over-year, driven by a 22% year-over-year growth in liquids production

Full-year 2016 production of 195.3 MMcfe/d, a year-over-year increase of six percent; December 2016 exit rate production of ~200.0 MMcfe/d represents an increase of ~9% as compared to December 2015 exit rate production

With Gulf Coast transport beginning in November 2016, natural gas basis differentials averaged ~$0.50 off of the NYMEX price for November and December 2016

For the fourth quarter of 2016, C3+ NGL pricing, before the effects of cash-settled derivatives, was ~56% of WTI and ~52% after the effects of cash-settled derivatives

In the Moraine East Area, placed the two-well Klever pad into sales – 5-day average sales rate of 10.4 MMcfe/d; 56% liquids

(1) Realized pricing for the fourth quarter and full-year 2016 are estimates and are subject to the finalization of the closing and financial reporting process.
(2) Natural gas liquids (C3+), ethane and condensate are converted at the rate of one barrel of oil equivalent to six Mcfe
(3) Includes the effects of derivatives not classified as discontinued operations. When including the results of our discontinued operations, the average net realized price for oil and condensate for the fourth quarter of 2015 and the full year 2015 were approximately $49.85 and $52.27, respectively.
